OVERVIEW

The question of the sustainability of coupling water and urban requirements is the subject of the engineering disciplines (hydrology and hydraulic structures) dealing with the themes of water in the urban environment and the associated demand for security, liveability and environmental protection. The objectives are the correct design and optimal management of urban drainage and water supply networks, of discharge outflows into receiving water bodies and of water saving and harvesting solutions.

AIMS AND CONTENT

LEARNING OUTCOMES

This module aims to provide the students with the capability of designing, from both the engineering and managerial point of view, water supply and drainage systems for the urban environment.

AIMS AND LEARNING OUTCOMES

The necessary theoretical and practical elements provided in this module for the design and management of water supply systems are the knowledge and understanding of basic hydrological and hydraulic processes, applied to solving simple construction and operational problems related to water supply networks (water supply, transport and distribution).

Similarly, the necessary theoretical and practical elements provided in this module for the design and management of urban drainage systems are the knowledge and understanding of basic hydrological and hydraulic processes, applied to solving simple construction and operational problems related to sewers and stormwater drainage networks (collection, coveyance and discharge of waste water and storm water).

The module also provides the basic necessary skills to gather and interpret relevant data for the design and management of urban drainage networks (e.g. data deriving from raingauge and flowgauge measurements) and their processing and interpretation.

Further objectives of this module include the ability to communicate information, ideas, problems and solutions to both specialist and non-specialist audiences, with reference to environmental and socio-economic issues linked with the course topics and having a relevant impact on the territory.

Finally, this module allows students to develop those learning skills that are necessary for them to continue to undertake further study in the field of civil and environmental engineering, with a suitable degree of autonomy.

TEACHING METHODS

This module is organised as a series of frontal teaching lectures, which include a few practical exercises about the design of simplified water supply and drainage network schemes.

SYLLABUS/CONTENT

WATER SUPPLY SYSTEMS 1) Analysis of the demand – consumption characteristics – estimate of water needs. 2) Drinking water resources: surface water. 3) Diversion and collection structures. 4) Storage: design and management of reservoirs. 5) Transportation: design of large pipes: calculations under steady flow conditions, pipes and special devices. 6) Water distribution networks: layout - criteria for tracing and laying pipes – hydraulic assessment of pressure networks: Hardy-Cross methods – pipes for water supply: materials, working pressures, dimensions, joints and special features – head and downstream reservoirs. 7) Private systems: Internal distribution systems, fire prevention systems.
URBAN DRAINAGE SYSTEMS 1) Design of urban drainage systems: engineering and managerial requirements. 2) Analysis and estimation of rainfall events: depth-duration-frequency curves – design hyetograph. 3) Evaluation of infiltration and runoff: practical methods to estimate storm water runoff. 4) Calculation of the flow rate in drainage networks: rational method, time of concentration method, storage method – critical network conditions. 5) Verification and design problem for drainage networks. 6) Construction of separate and combined networks, wastewater management.

EXAMS

EXAM DESCRIPTION

The examination is composed of a written and an oral part. Access to the oral part is obtained after the written part is successful with a minimum score of 18/30.

ASSESSMENT METHODS

In the written part, the assessment of the student qualification is performed by evaluating the correctness of the solution provided for two practical exercises concerning the design of simple water supply and drainage network schemes. Examples of the test and a few solved exercises are available on AulaWeb. For the oral part, the assessment is performed based on the correctness of the exposition and discussion of design and/or conceptual topics concerning the whole content of the course.
